  • Beam-off motion thresholds in radiation therapy based on breath-hold level determination
    Patent number: 11878189
    Abstract: A computer-implemented method of performing a treatment fraction of radiation therapy comprises: determining a current position of a target volume of patient anatomy; based on the current position of the target volume, computing an accumulated dose for non-target tissue proximate the target volume; determining that the accumulated dose is less than a current value for a dose budget of the non-target tissue; and in response to the accumulated dose being less than the current value for the dose budget, applying a treatment beam to the target volume while the target volume is in the current position.
    Type: Grant
    Filed: August 31, 2022
    Date of Patent: January 23, 2024
    Assignee: SIEMENS HEALTHINEEERS INTERNATIONAL AG
